Abstract

Disclosed is a valve / seal assembly that is adapted for use in a variety of applications, such as for example, medical, consumer beverage, pharmaceutical containers, automobile, household appliance and marine. The disclosed valve includes, inter alia, a valve housing having an upper body portion and a lower body portion and a generally spherical valve member. The upper and lower body portions of the housing define an internal chamber for accommodating the valve member and a central axis for the valve. The generally spherical valve member is seated within the internal chamber of the valve housing and has an axial bore extending therethrough. The valve member is mounted for movement between an open position; wherein the axial bore of the valve member is axially aligned with the inlet and outlet ports of the valve housing, and a closed position; wherein the axial bore of the valve member is out of alignment with the inlet and outlet ports of the valve housing. The valve assembly further includes a camming mechanism that is operatively associated with the valve housing and the valve member for moving the valve member between the open position and the closed position.
